Authorities say a man and woman left the woman’s name and telephone number in the guestbook of a South Florida art gallery before stealing about $6,000 USD worth of jewelry.

Palm Beach police say 24-year-old Megan Ohara and 19-year-old David Ziskoski took a bracelet and a ring Sunday from the Attila JK exhibition at the ICFA Gallery that belonged to the artist. They were spotted a short time later at a nearby grocery, and police reported finding the jewelry in the woman’s purse.

Officers found multiple fake email addresses, including “[email protected]老域名购买” and at least one obscene drawing in the gallery’s guestbook. The South Florida Sun Sentinel reports that two of the fake emails included the name “Meg” and one included Ohara’s phone number.

The newspaper reported that Ohara and Ziskoski admitted to the theft and guestbook entries.

According to the arrest report, Ohara said, “If I knew they cost that much, I wouldn’t have taken it.”

Ohara and Ziskoski were arrested and charged with grand theft of under $10,000. Jail records didn’t list attorneys.

Facebook profiles appearing to belong to Ohara and Ziskoski show that both attended university in New York City. Ziskoski’s page says he is currently living in Philadelphia and working at GE.

Global News spoke to Ildiko Varga, owner of the ICFA Gallery. She said she wasn’t present at the time of the incident and declined to answer any further questions. Calls to Attila JK and the Palm Beach Sheriff’s Office were not returned.
